7' To it may comem:

v Be it known that I, EDGAR STEINBERG, a citizen of the German Republic, residing at Berl n-Wilmersdorf, Germany, have invented certain new and useful Improvements in Light Radiators for Medical Purposes, ofn which the following is a specification.

The object of the present invention is to produce alight radiator for medical pur- 1 poses of a shape ands'tructure which allows it to be conveniently and safely brou ht close to the body of the patient, and the 1n- .vention consists in'the provision of a spherical reflector which is truncated in an oblique plane relative to a ventilation shaft whereby the reflector is surmounted, the truncated side" of the reflector being closed by a M I flanged, conical projecting tube whose length is about equal to the diameter of the reflec- 3 tor and which is continued by a plain tube of about the same length. The li ht is obtained froman electric arc, the car 11 holders being arranged so as to project into the reflectorthrough a single, easily covered aperture so that the am will be effectively enclosed and so that all spluttering will be confined to thereflector. v r

Fig. 1 of the accompanying drawings represents a side view, partly in section, of one form of construction of the apparatus, and

" Fig. 2, a side view of anothe'rform.

A trlmcated spherical reflector basin 4 i8 surmounted by a ventilation shaft 9 for cad.-

ing ofi the heatproduced by an electric arc lam arranged with. the arc in thece'nter -of-t e cas' The casing .1s' truncated obliquelyrelati-ve to the ventilation shaft, and the-truncated,

is closed-by a flange 12 of which is formed. on the. wide end'of .a conical light-projecting tube, length of the tube 5 is about equal side of the'casin substantial width 5. The

The l a holders can be introduced. together into the in alignment with the shaft.

mp is arranged so that the carbon reflector casing through an aperture which can easily be covered, so that the splurting of the arc will not inconvenience the patient however closely the lamp is approached to v the. latter.

Fig. 1 shows the holders 3 introduced through the ventilation shaft 9, while in Fig. 2, where the carbons 13 are arranged at right angles to the holder arms 14, the latter enter 6 the reflector at 15 through a separate slit which is covered by a casing 9 containing the lamp mechanism.

The projecting tubes are arranged in alignment with the arc. The comparatively what varied to suit different circumstances. 7 v

Fig. 1 shows the tube at a greater angle relative to the flan e 12 than in F5. 2.

The means 0 support may a so be varied. The lamp shown in Fig. 1 is adapted to be suspended, for instance from a ceiling, and kit may be steadied by an arm 11 connected to a vertically adjustable uprlght 1' fitted m a suitable stand.

The stand 1 shown in Fig. 2 is adapted to I carry the lamp without other support, but the apparatus may be steadied by means of a stay. 10 connected at one end to the stand, and at the other endtofone of the project- 'ing tubes.

I claim: a

vent1lation shaft connected to said reflector in alignment with the center of thelatter and at an angle to the plane in which the 6 reflector is truncated, a conical projecting tube. of substantially the same length as the diameter of the reflector, a flange of su.b'- stantial width formed at the. wideend of said tube, the tube being connected by means of said flange to the reflector as a closure for the truncated side of the latter, a' plain 1. A light radiator for medical purposes '7 com rising a truncated spherical reflector, a

( projecting tube substantially equal in length 2. A light radiator according to claim 1 to, the conical tube and arranged as a conhaving the carbon holders arranged so as to tinuation of the same, and carbon holders arproject through the ventilation shaft into 1 ranged so. as to Project into the reflector the reflector, substantially as' and for the through a single aperture for the produc- Ipurpose set forth.

tion of an electric arc in the center of-the reflector. 4 EDGAR STEINBERGQ I
